Hello
This is the setting question when using LTC2949 chipset.
I thought if I set RS1GC, RS2GC or BATGC, I could read BAT value or I1 or I2 value as compensated value.
However, it does not seem to change(1.609) even if you change the GC value.
Below is the linduino SPI log of the BAT value when changing the BATGC value.
(For setup function, only the 100ms continuous measurement setting and the BATGC setting are performed. )
Which part did I set wrong?
